The Need to Promote Olfactory Health in Public Health Agendas Across the Globe

Abstract

Background: A good sense of smell is essential for physical and mental health, and social wellbeing; however, across the globe, regardless of the setting, national public health agendas never consider smell health. This review aims to summarise the wide-reaching impact of smell health in public health. Methods: Narrative review of the literature has been undertaken by leading opinion figures in the field of olfactory health. Results: The sense of smell should be promoted as an essential pillar of health, as it enables good nutrition and cognitive and psychological well-being. To improve smell health internationally, a focus on education and awareness, research and targeted public health policies is needed. Conclusions: We recommend developing smell health educational programmes and awareness campaigns, introducing smell screening and developing and implementing smell health policies across sectors of society. Efforts are needed to ensure equity, diversity and inclusivity for all people, particularly given the current demographic as those seeking help are typically not from a diverse cross-section of the community.
